February 20, 2020


We’re closing this section of the motorway so we can demolish Old Slade Lane
bridge near junction 4b, which will be replaced later in 2020.


The signed diversion
route for the weekend will utilise the M25, A3113, A3044 and the A4



The M4 will be closed in both directions between
junctions 4b to 5 between
8pm Friday 21 February 2020 until 6am Sunday 23 February 2020
